Affected packages

• PyPI apache-airflow-providers-cncf-kubernetes: < 10.17.0 → fixed in 10.17.0

Description

JWT tokens that were used by workers in Kubernetes Executors have been exposed to users who had read only access to Kuberentes Pods. This could allow users with just read-only access to perform actions that were only available to running tasks via Task SDK and potentially allow to modify state of Airflow Database for tasks.
